Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple different types of navigation sensors are used to detect various navigational hazards, then the detection capability and reliability are improved, but the system complexity and difficulty in determining the most immediate threat increase
Solution Approach 1:
The patent combines multiple different types of navigation sensors (radar, sonar, LIDAR, cameras, GPS) into a single integrated navigation system that processes all sensor data through a common threat assessment algorithm. This merging approach maintains the detection reliability of individual sensors while reducing system complexity by providing a unified view of navigational hazards through a single display interface that prioritizes threats by immediacy.
Solution Approach 2:
The navigation system is designed with multi-functionality to handle various types of navigational hazards (shallow water, obstacles, other vessels, weather conditions) using a single integrated platform. The system universally processes data from multiple sensor types and applies a common threat assessment methodology, eliminating the need for separate dedicated systems for each hazard type while maintaining comprehensive detection capability.
2Measurement precision
If multiple different types of navigation sensors are used with dedicated display views for each, then the detection precision for each hazard type is improved, but the ease of operation and quick assessment of immediate threats deteriorates
Solution Approach 1:
The patent merges multiple dedicated display views into a single unified display interface that presents all navigational hazards in a consolidated format. The system maintains the detection precision of individual sensors by processing their data separately through appropriate algorithms, then integrates the results into one display that ranks hazards by threat immediacy, allowing pilots to quickly assess the most critical threats without switching between multiple views.
Solution Approach 2:
The system adds a new dimension to hazard presentation by incorporating threat immediacy ranking into the display. Instead of showing hazards in separate dedicated views as in conventional systems, the unified display organizes hazards along an additional dimension of priority/urgency, allowing pilots to immediately identify the most pressing threats while preserving the detection precision of individual sensor types through maintained data processing integrity.
3Reliability
If multiple safety alarms are generated for different navigational dangers, then the comprehensive safety monitoring is improved, but the pilot workload and complexity in managing alarm settings increases
Solution Approach 1:
The patent combines multiple safety alarms into a single integrated alarm system that monitors all navigational hazards simultaneously. The system generates comprehensive safety alerts for different hazard types (shallow water, obstacles, vessels, weather) through a unified alarm management interface, maintaining comprehensive safety monitoring while reducing pilot workload by eliminating the need to manage separate alarm settings for each hazard type.
Solution Approach 2:
The alarm system is designed with universality to handle multiple hazard types through a single multi-functional interface. The system can generate and manage various alarm conditions (proximity warnings, collision risks, environmental hazards) using one standardized alarm management system, preserving comprehensive safety monitoring while simplifying pilot interaction through consistent alarm presentation and management procedures.
